Brief Summary:

Allergic rhinitis is a complex chronic inflammatory disease, it always presents with nasal obstruction, nasal itching, sneezing and runny nose. Whether in adults or children, rhinitis is a complex disease. The prevalence of allergic rhinitis in Taiwan is about 24-29%. Taiwan is a developing country. It is a hot and humid country. In developing countries, industrialization, air pollution makes the constantly increasing number of patients with rhinitis. Penghu in 1994 for children aged 7 to 14 by the study found that among 7599 people, 1766 people have allergic rhinitis, about 23.2%. Allergic rhinitis is a complex chronic disease. So, it become a diagnostic challenge, its prevalence always underestimated. The prevalence of rhinitis has increased in recent years. The phenomenon of underestimate is caused by variety of personal and environmental factors. Allergic rhinitis had increased direct and indirect social and economic burden.

Geographic tongue is a benign tongue performance. Geographic tongue has been reported their relevance to allergy. Geographic tongue is a chronic tongue situation. The causes of geographic tongue still remains unknown. Allergic rhinitis is a diagnostic challenge to clinicians. The investigators hope that geographic tongue could play a role in the diagnostic of allergic rhinitis. The prevalence of geographic tongue in the United States is about 1.8%, white Americans and Mexicans have a higher incidence rate. This study will investigate the relevance between allergic rhinitis and geographic tongue. The investigators will analyze the relevant gender, age, severity of inspection reports. The research results wound provide an important reference to the diagnosis of allergic rhinitis.
